Iranian President Mahmoud Ahmadinejad said on Thursday an Israeli strike on Syria would be considered an attack on the whole Islamic world that would bring a "fierce response", state television reported.

"If the Zionist regime commits another stupid move and attacks Syria, this will be considered like attacking the whole Islamic world and this regime will receive a very fierce response," Ahmadinejad was quoted as saying in a telephone conversation with Syrian President Bashar al-Assad.

The president made the comments after Israel struck Beirut airport and military airbases and blockaded Lebanese ports in reprisals that have killed 55 civilians in Lebanon since Hezbollah gunmen captured two Israeli soldiers a day earlier.

"He (Ahmadinejad) also said it was a must for the Organisation of the Islamic Conference to become more active regarding the new crisis created by the Zionist regime," state television reported.

Riyadh faults Hezbollah for current crisis Saudi Arabia on Thursday blamed "elements" inside Lebanon for the violence with Israel, in unusually frank language directed at guerrilla group Hezbollah and its Iranian backers.

"A distinction must be made between legitimate resistance and uncalculated adventures undertaken by elements inside (Lebanon) and those behind them without recourse to the legal authorities and consulting and coordinating with Arab nations," a statement carried by the official news agency SPA said.

"These elements should bear the responsibility for their irresponsible actions and they alone should end the crisis they have created."
